Working with Addons

Firefox includes some pretty advanced features for web browsing. However, you can extend the features available in Firefox with two methods:

♦ Extensions

A plug-in provides functionality to Firefox for handling different types of multimedia. A plug-in displays the results directly in the Firefox browser window, instead of using an external program that runs outside the browser. When browsing you often may be prompted by Firefox to install a particular plug-in to view content on a web page. Firefox can detect

which plug-in is required for a specific type of multimedia content. Chapter 11, "Using Audio," and Chapter 12, "Using Video," explain how to add popular plug-ins (such as Macromedia's Flash plug-in) to your system.

Firefox also supports a concept called extensions, which refers to extra features that aren't included in the main Firefox browser. Extensions allow you to pick and choose advanced features that can enhance your browsing experience.

Select Tools O Add-ons to open the Add-ons dialog box, shown in Figure 8-6.

The Extensions section shows the currently installed extensions. The only extension Ubuntu installs by default is the Ubuntu Firefox pack, a customized set of features for Ubuntu.

Click the Get Add-ons link (if you are connected to the Internet) to open a web page that lets you browse to see what extensions are available. You'll see a list of common extensions that are recommended to install, plus a link to get Ubuntu-specific extensions. When you click the Ubuntu extensions link, the Ubuntu Install/Remove Extensions dialog box appears, shown in Figure 8-7.

You can peruse a list of extensions you can add to Firefox and select the ones you think might come in handy.

Clicking the Browse All Add-ons link takes you to the main Firefox Add-ons web page. You can search through all of the available add-ons here. Be careful, though, because there's no guarantee that all of the add-ons will work properly in the Ubuntu Firefox environment. All you can do is download and try them out.
